■ •rices between them. The kinds of corn in cultivation about Gua-
najuato are described by Prof- Dugea as the mats arriveno } with hard
and shining kernels; man cownnut, softer and less shining, either yel-
low, black, or red ; metis molonco^ resembling the last, but with smaller
kernels, growing in the "bad lands," and the difference probably due
to the poverty of the soil; and a popcorn, mtus roswo. All of these
are affirmed to be very unlike the mats de coyote, whirh appears to
be known only in a wild state,
As shown by I>r. Sturtevant in the Report of the N. Y. Agricul-
tural Experiment Station for 1N8JJ, the varieties of corn cultivated
generally by the Indians of Mexico all come into the group desig-
nated by him as "soft corns" ( u Zea* amylacea"), in which the broad
flattened kernels are composed wholly of starchy matter in addition
to the embryo, A peculiar kind was found by Dr. Palmer at the
Indian village of San Padro, Guadalajara, of which Dr. Sturtevant
forms the distinct group of "starchy sweet corns" (" Zea* amylea-
mccharata "), intermediate between the sweet and soft corns, having
a wrinkled exterior and the summit of the kernel corneous. It is
evident that so far as the grain is concerned these have little resem-
blance to the metis de coyote*
4. Notes upon a Collection of Plants from the Island of
During the visit of the IT. S. Eclipse Expedition of 1889 to the
island of Ascension, Mr. E. J. Loomis of the Nautical Almanac Bu-
reau, Washington, made a collection of such plants as chanced to at-
tract his attention. Though very small, it adds some species to the
previously known flora of the locality, a full account of which is given
by Mr. W. B. Hemsley in the botanical report of the voyage of the
fii Challenger," The vegetation of the island, as there stated, is re-
stricted almost wholly to " Green Mountain/ 11 an elevation of nearly
3,000 feet altitude, which condenses the moisture of the southeast
trades, and is consequently subject to frequent rains and fogs. At
about three hundred feet below the summit the peak is encircled by
a nearly level road, known as "Elliott's Pass," which generally fol-
lows the very irregular contour of the mountain, but is occasionally
carried through a spur by means of a tunnel. When these tunnels
are short, they are lined throughout, roof and sides> with the most
delicate and beautiful ferns, as are also the longer tunnels so far as
daylight extends. It was on this part of the mountain that much
of the collection was made*

The entire pha?nogainous flora native to the island, as given by Mr,
Hemslcy, includes but twelve species, and ten of these are marked
by him as only doubtfully indigenous. The two other species, Jhul-
yotis Adscensionis aud Euphorbia oi-igaiioides^ are endemic. The
cryptogamous flora is somewhat more extensive, the same authority
giving a list of fourteen ferns (including a Lycopodiitm), thirty-five
mosses and hepatics, and a dozen lichens*
The following is a list of the species of every kind collected by
Mr. Loomis, of which those in italics are without doubt introduced
plants. The species of ferns described as new have been submitted
to Prof. Eaton and to Mr, J. G. Baker. The mosses were determined
by Prof. C. R. Barnes, the single hepatic by Prof. L. M. Underwood,
and the lichens by Prof, Farlow. It is to be regretted that the oppor-
tunity could not have been improved to make a larger and more
complete collection of the plants of the island, for it is probable that
a thorough search would increase considerably the number of indige-
nous species now known.

Senehiera didywa, Pers.
Oxalis cornicuhda, L,
Rubus nanus. Stems very short (1 or 2 inches high), from a
woody caudex, erect, armed with numerous short recurved prickles,
about 3-flowered at the summit: stipules narrow, acuminate, entire or
sparsely toothed ; petioles short, pubescent and prickly; leaves mostly
simple and rounded, subcordate at base, unequally and suhincisely ser-
rate, somewhat o-lobed or sometimes ternate, sparsely villous above,
prickly on the veins beneath: calyx small (about 4 lines broad), the
base prickly : carpels rather numerous, on a depressed receptacle, gla-
brous ; styles short. — Described from a single specimen found near
the entrance of a tunnel in Elliott's Pass. It appears to be a very
distinct and peculiar species of a genus not otherwise represented in
the flora of the islands of the South Atlantic,

Asplenittm Ascensionis. Stipes slender, tufted, an inch 1. r
less, oakedj ilull brownish green; frond 3 t«» 6 inches long, often rout-
ing at the apex, 6 to 10 lines broad, the rhachis channelled shov
and narrowly winged ; pinna* about 20 (15 to 2^) on each side,
very invgular in r-hai »e ( nearly as in A. fragile), in the middle of the
frond somewhat quadrilateral and nearly twice longer than broad,
often more or less deeply lobed at hase on the upper side, obtu><\
irregularly and obtusely few-toothed or the lower margin entire, the
lowermost usually round-deltoid^ nearly equilateral and often lobed
both sides, the uppermost becoming cuneate-obovate : sori linear-ob-
long, oblique, 1 to G ou each side, — This adds another species to the
closely allied A. viride group, intermediate between A. fragile and
J. ragans* It is probably the same as the A. dentaium reported by
Bory as collected on the island by D'Urville. Mr, Baker informs me
that he also finds a specimen in Herb- Kew, among their A*fragile f
which was given by " Don " (probably George, the younger, and col-
lected by him on his trip to Sierra Leone) to Lindley in 1831.
Nephrodium mollk, Desv. Specimens very variable and mostly
2si rHRODitnvi (?) visciDUjL More or less densely glandular-fibril-
lose throughout; stipes from a slender creeping rhizome, brown, about
an inch long, bearing a lanceolate acuminate pinnate frond 3 inches
long ; pin me (except the upper ones) cleft nearly or quite to the mid-
venij the thin broadly oblong segments (1 to 2 lines long) obtuse, more
or less crenate-serrate, glandular-villous beneath, — A single speci-
men, not in fruit, and the genus consequently indeterminate- Though
strongly marked by its glandular-fibrillose character, it is not recog-
nized by either Mr. Baker or Prof. Eaton, The former thinks it
a starved Nepkrodiumj but "it cannot be N. Ascemianis" the only
species excepting the last that is known from the island,
